Nup.Have finally figured out the problem.Dodgy plug on the ECU.Car ran like a train all day.Only problem was I forgot to wind the boost back up and it was only running 10psi.It usually runs 15-17psi and comes on far more savagely.

Next round of mods concern making it go around corners better- so front end grip.And trying to get rid of some lag which will initially mean an exhaust housing/dump pipe mod.

The S13 rear coilovers have a 2 stud 8mm setup where the Skyline has a 3 stud 10mm.So the top plate has to be redrilled to suit.

I am tapping the plate so the bolts will be captured and I won't need to be in 2 places at once.I'm using a 10mm x 1.5mm pitch #2 tap instead of a #1 or taper tap. it works much better with the soft aluminium, with plenty of WD40 as a lubricant.

The set screws are 10x30 stainless steel with a spring washer and nut.

in my opinion If you want handling dont use them! i have just removed them from my dr30 the geometry is all wrong.. unless you fix the outer tie rod angle and the toe in on turns it will hamper your efforts.. its seems temping at first but seriously you will be better of to shorten your oe McPherson's weld a thread to them and put z31 koni's or such in its far better for the cars handling

just some advice having been there you seem handy with tools so you could make it work but suspension is what i do and i couldn't justify the mods needed over re installing the oe struts turned into adjustable's.
